Try this (untested):
$inputFilter->add($factory->createInput(array(
'name' => 'somevalue',
'required' => true,
'validators' => array(
array(
'name' => 'Digits',
'break_chain_on_failure' => true,
),
array(
'name' => 'Between',
'options' => array(
'min' => 1,
'max' => 50,
),
),
),
)));
This sets up two validators. The first checks to ensure we have only
Digits, and will halt the chain if it fails. If we do have only digits,
we then hit the "Between" validator, and the value is tested to see if
it lies between the min and max provided.
